[Comparing the pain severity caused by muscular injection of Tramadole in Z and bulb methods]

ABSTRACT

Pain, rather than any other problems, would persuade people to pursue remedy and treatment. Muscular injections are among pain producing factors. This technique of prescription can be followed by some complications from which pain is the most prevalent one. This study was performed to compare the pain severity caused by muscular injection of Tramadole in Z and Bulb methods. This is a clinical trial study in which 90 women who referred to the emergency ward of Shahid Beheshti hospital in Yasooj in 2006 were randomly selected. Data collection instrument was questionnaire. The pain severity was evaluated by visual scale. Data were analyzed by descriptive statistical method, independent T and chi square test using SPSS software. Mean of pain severity in bulb method was 2.84 +/- 1.242 and in Z method was 4.56 +/- 1.659. The independent T test indicated that the differences in pain severity in two injection methods were statistically significant [p=0.036]. No significant differences were found between age, educational level, job, marriatal status, number of previous injections and BMI of samples between two groups. Bulb method injection induces less pain in comparison with Z method; therefore it is an ideal method for muscular injections. As such, health care workers, especially nurses, can, through this method, minimize the patients' pain, which is one of the most important injection complaints
